Gait Event Detection in Real-World Environments for Long-Term Applications

This page provides the library that can be used to detect gait events from 3-axis accelerometer signals collected during walking or running.

The library can be found here: Link to Github repository

List of Specifications

Activities: Walking and running

Placement of 3-axis Accelerometer: Anywhere around the ankle in any orientation.

Sensitivity of the Accelerometer: (+-) 4g or more. Please specify. Please also check if the accelerometer signal has saturated during intense activity such as running.

Sampling Frequency: Preferred - 128 Hz [A Sampling frequency of 50Hz and above is acceptable. Please specify.]

Input data: AccX, AccY, AccZ [Accelerometer signals from the X, Y and Z axes, respectively.]

Input data format: abc.mat or abc.csv [Data in Matlab format or comma separated text file.]

NOTE: The data should consist of ONLY walking and running segments of the signal. Segments corresponding to inactivity or any other activity should be removed from the signals prior to data submission.
